Abstract: In this work I have identified the most important elements in Kant' s argumentation in his Transcendental Analytic, that is, on one side, the intuitive representations (sensations, empirical intuitions, pure intuitions and appearances) covered in his Transcendental Aesthetic, and, on the other side, as much the discursive representations (concepts) as the operations (associated to unity, mIes andjudgments) treated in his Transcendental Logic. In relation to each of theses elements, I have made a confrontation between parts of Kant's manifold works where they are explained, searching to identify, in that multiplicity of descriptions, informations and/or possible incoherencies, aimed to comprehend each one of them in a clear and precise way. Finally, I exposed how Kant operates with these elements to solve his fundamental problem relatively to the possibility of synthetic judgments, first in his Schematism of the Conceptions and, afier, in his Principies of pure understanding
